碩士 === 國立中山大學 === 環境工程研究所 === 97 === The drinking water treated by water treatment plant (WTP) usually has an
excess of assimilable organic carbon (AOC) in distribution systems in south Taiwan.
They will cause the growth of heterotrophic plate count (HPC) and deterioration of
water quality in pipeline of distribution systems. Recently, part of traditional
purification processes were changed into advanced processes in WTP. The past
researches showed the combined advanced processes ultrafitration (UF) / reverse
osmosis (RO) in south WTP in Taiwan has the removal problems of AOC in above
UF / RO processes because the organic compounds in raw water caused a fouling
layer which was formed on the membranes surface. These problems made the
back-wash frequency increasing, short membrane life and raising cost.
The study combines activated carbon and membrane bioreactor (MBR) to
explore the removal efficiency of drinking water in laboratory. The system showed
the removal efficiencies of dissolved organic carbon (DOC) and AOC were 57%
and 36%, respectively in average. More, the system showed the removal
efficiencies of DOC and AOC were 81% and 66%.
The results of this research showed good removal efficiency was found in
AOC and DOC. Good quality of biological stability, removal of organic compounds,
low cost in building and maintaining were reached.
